You do you, girl.

After Katy Perry released a music video teaser for her next single, "Birthday," we knew we were in for her weirdest music video yet—which is saying a lot, because she has a long-running history of over-the-top videos that are basically super strange short films that cinema students could write entire theses on (and, given today's college classes, probably have). And sure enough, it is...in all its eight-minute glory.

Here's what you need to know: Katy dressed up in a few elaborate costumes—a mustachioed DJ, an elderly go-go dancer, a very sad clown—and crashed celebrations (allegedly real, though we'll let you be the judge of that) while pretending to be the "world's worst birthday party entertainers." The irony is, of course, that Katy would obviously be the world's best birthday party entertainer. But not like this.

Her get-ups are so beyond believable (that nose! those hotpants!), she's entirely unrecognizable. Seriously, who knew one of the prettiest girls in pop could convincingly play a creepy middle-aged man? And is anyone else as impressed by her acting abilities as her killer voice? If she ever needs a backup career—which will be never—she should head to Hollywood.
